Smi Mptool Sm32x Sm34x Smi Mass - Production Tool

Here is a quick reference guide based on actual controller IDs (identified via ChipGenius):

| Controller | Recommended MPTool Version | Notes | | --- | --- | --- | | SM3257EN | SM3257EN_V2.5.xx | USB 2.0, very stable | | SM3267AE | SM3267AE_V2.5.xx | USB 3.0, good for MLC | | SM3268AB | SM3268AB_V2.5.xx | USB 3.0, TLC support | | SM3271AB | SM3271MPTool_V2.5.xx | Low-cost 3D TLC | | SM3280AB / SM3281BB | Star_SM3281_V2.5.xx or SM3280MPTool | Fastest USB 3.1, requires smi_star variant | | SM3282 | SM3282MPTool | SSD-like performance |

Note: The "Star" prefix (e.g., Star_SM3281MPTool) indicates a special version for SMI's "Star" series controllers, which have different firmware protocols. Do not use standard SM3280 tools on Star controllers.

When you extract an SMI MPTool folder, you will see several critical components. Understanding them is half the battle.

| File/Folder | Purpose | | --- | --- | | main.exe / sm32x_*.exe | The main GUI application. | | UFD_MP folder | Contains configuration files (setting.set) and default settings. | | ISP folder | Image System Program – the firmware binary files (ISP_SM32x_xxx.bin). | | DLL folder | Dynamic link libraries for NAND detection. | | Debug.log | Log file generated during mass production. | | CID folder | Card ID database for manufacturer settings. | smi mptool sm32x sm34x smi mass production tool

| Family | Common Controllers | USB Speed | |--------|--------------------|------------| | SM32x | SM321, SM324, SM325, SM326, SM327 | USB 2.0 / USB 3.0 | | SM34x | SM341, SM342, SM343, SM346, SM349 | USB 3.0 / USB 3.1 |

These controllers are widely used in budget to mid-range flash drives from brands like PNY, Kingston (some models), ADATA, Transcend, and generic OEM drives.

The SMI MPTool is the silent workhorse behind high-volume storage-device manufacturing — a specialized mass-production utility engineered for efficiency, repeatability, and scale. Focused on the SMI SM32x and SM34x controller families, this tool stitches together firmware provisioning, device configuration, bad-block management, and quality gating into a single, automated pipeline that transforms raw NAND into finished, production-ready flash drives and embedded storage modules.

Step 1: Prepare the tool. Open the MPTool folder and right-click the .exe → Run as Administrator. Here is a quick reference guide based on

Step 2: Open settings. Click Setting, enter 320, then go to the Main Setup tab. Configure your Vendor Name and Product Name. Keep the default Serial Number formula unless you have a reason to change it.

Step 3: Configure NAND scanning. Navigate to NAND Flash Setting. Under "Erase Info," select:

Step 4: Partition setup (optional). If you want a simple storage drive, leave "Public Partition Only" selected. If making a bootable drive, set the "CD-ROM" size and point it to your .iso file.

Step 5: Save and return. Click OK to save. You will return to the main screen. Note: The "Star" prefix (e

Step 6: Connect the device. Insert the USB flash drive. Click Test (or Scan USB) . The drive should appear in the tool's list. You will see information like "Found 1 Device."

Step 7: Start mass production. Click the Start (or Space) button. A progress bar will appear:

Step 8: Completion. When the box turns Green (OK) , success! Unplug the drive, re-plug it, and Windows should mount it as a fresh storage device.
